Options to separate selected phrases

Sometimes I don't understand a phrase but I want each word in the phrase to be a separate flash card. Could it be possible, if a phrase is selected, to cycle through the options of selecting the whole phrase, having each word as a separate selection and deselecting all, as currently when you select a word followed by another word and then tap again it switches to a single word selection again. Also a selection delay of say 3 seconds before saving a flashcard so it doesn't save duplicates because you have been trying to select a phrase?
